AMP amp-autocomplete - 单击时转到 url答案

【问题标题】：AMP amp-autocomplete - go to url when clickedAMP amp-autocomplete - 单击时转到 url
【发布时间】：2020-08-10 21:17:21
【问题描述】：

我试图让 amp-autocomplete 直接转到单击时从 json 列表中获取的 url。 href 包含在结果中，但是当单击结果时，它只是将其添加到输入框中，而不是直接。

我试过on="tap:AMP.navigateTo(url='{{url}}')" 似乎没有做任何事情。不确定 amp 是否可以做到这一点？

<form class="sample-form" method="post" target="_top" action-xhr="https://amp.dev/documentation/examples/api/echo">
  <label>
    <span>Search for</span>
    <amp-autocomplete filter="token-prefix" filter-value="h1"  min-characters="2">
        <input type="search" name="h1">
      <script type="application/json">
            {
                "items":[
                        {
                            "h1":"page1",
                            "url":"page-1-url"
                        },{
                            "h1":"page2",
                            "url":"page-2-url"
                        },
                        {
                            "h1":"page3",
                            "url":"page-3-url"
                        }
                ]
            }
      </script>
            <template type="amp-mustache" id="amp-template-custom">
                <div class="slug-item" data-value="{{h1}}">
                        <a href="{{url}}" on="tap:AMP.navigateTo(url='{{url}}')">{{h1}}</a>   
                </div>
            </template>
    </amp-autocomplete>
  </label>
</form>

有趣的问题。

一开始，我尝试使用 CSS 解决问题，例如为链接设置高 z-index，但没有奏效。

最后，我选择了 amp-autocomplete 中的 on="select" 事件。我希望这个选项适合你：

我已经在手机和电脑上测试过，效果很好。
